Shawnee Police Detective Ronnie Wilson said Antonio Maurice Sambrano, 18, has been arrested in the case and is being held without bond in the Pottawatomie County Public Safety Center on a complaint of first-degree murder. A formal charge has not been filed.

It was just before 1:30 p.m. Wednesday when emergency crews responded to a shots fired report at building 11 at Chapel Ridge Apartments, 130 E. 45h Street.

According to probable cause affidavit, the shooting occurred in unit 11-F, where Harjo reportedly resided.

Harjo was found in the front yard area of that apartment unit with a gunshot wound and the affidavit shows Harjo was loaded into an ambulance. When asked at the scene who shot him, Harjo allegedly told a police officer that “Antonio shot me,” the affidavit reads.

Harjo was transported to OU Medical Center in Oklahoma City, where he died. He was reportedly shot through his torso; an official cause and manner of death is awaited from the Office of the Chief Medical Examiner.

Police investigating the scene reported there was a blood trail from the yard of the apartment to the couch in the living room of unit 11-F.

Based on the arrest affidavit, detectives interviewed at least two witnesses — a woman that Harjo was in a dating relationship with and her cousin, who both reportedly resided in the apartment with Harjo.

Sambrano reportedly fled the scene in a red, extended cab Chevrolet pickup but was later taken into custody. Sambrano allegedly told detectives that he left the apartment after a fight there but said he never heard a gunshot and didn't know who shot Harjo.

Complete case reports will be turned over to the district attorney's office for consideration of formal charges.

In the moments after the shooting, several nearby locations, including Shawnee Middle School, Gordon Cooper Technology Center and even a local daycare center, were reported to be on lockdown.
